# What Is a Change in Velocity Called?

**A change in velocity is called acceleration.** It can be positive or negative, though negative acceleration, or a decrease in velocity, is often referred to as deceleration.

Acceleration is the rate of change in velocity of an object over time. It is the net result of all the forces acting upon the object. The application of a physical force, such as hitting a ball with a bat, causes it to accelerate, as long as the force is sufficient to overcome the inertia of the object. A falling object accelerates at a constant rate due to the force of the Earth's gravity, until the force of gravity is matched by the force of air resistance. At that point, terminal velocity is reached. The object continues falling at a constant speed, and its acceleration is considered to be zero.

Q:
## What Is the Formula for Acceleration?

A: The formula for acceleration is given as a = (v2 - v1) / (t2 - t1), where "a" denotes the acceleration, "v2" indicates the final velocity, "v1" represents ... Full Answer >Filed Under: -
Q:
## What Is the Definition of Constant Acceleration?

A: Constant acceleration is a change in velocity that doesn't vary over a given length of time. If a car increases its velocity by 20 mph over the course of a... Full Answer >Filed Under: -
Q:
## How Do You Calculate Acceleration?

A: To calculate acceleration, divide the change in velocity by the total time. Acceleration values are expressed in units of velocity per time, including mete... Full Answer >Filed Under: -
